In September 2023, a homeowner in Clapham asked five renovation contractors to quote a rear kitchen extension. Three visited the property. Two sent quotes back.
The gap between those two quotes was £43,000. Not a difference in specification. Not one quoting a garage conversion and one quoting a full structural extension. Both quoting the same drawings, the same back wall opened up, the same bifold doors onto the same garden. Forty-three thousand pounds apart.
She accepted the lower quote. Six weeks into the build, three variation invoices arrived: structural steel not included in the original price, building regulations application not included, bifold doors not included because “those were quoted as an allowance, not a fixed price.”
The final cost was £11,000 above the higher of the two original quotes.
The problem was not that she chose the wrong contractor. The problem is structural. Finding a renovation contractor in London a real one, with the credentials, the project history, and the pricing discipline to deliver what they quote has always required more effort than it should.
QuoteMyRenovation was built to fix that.
We match London homeowners with vetted renovation specialists by trade, borough, and project type. We send your brief to up to three contractors who have completed comparable work in your area. We brief homeowners on realistic costs before quotes arrive, so the comparison is meaningful. We do not cold-call you. We do not sell your details.
Submit your brief and receive up to three matched quotes within five working days.
Why Is Finding a Renovation Contractor in London So Difficult?
London has more renovation contractors than any other city in the UK. It also has more ways for a homeowner to have a poor experience, and most of them begin at the same point: the initial search.
General directories return thousands of listings with no way to filter by borough, by project type, or by whether the contractor has actually completed a project like yours nearby. Lead platforms sell your contact details to multiple contractors, triggering a wave of calls from builders who know nothing about your project and may never visit your property. Recommendations from neighbours work until the contractor they used is fully booked or does not cover your trade.
London renovation is also more complex than renovation elsewhere. Planning authorities vary borough by borough: what Westminster permits, Wandsworth may not. Conservation areas require different materials and different consents. Period properties the Victorian terraces, Georgian townhouses, Edwardian mansion blocks, and mansion flats that make up most of Central and South-West London’s housing stock need contractors who understand how they were built and what they require. The answer is not more listings. It is a better match.
How QuoteMyRenovation Works for London Homeowners
QuoteMyRenovation operates on a simple model: you submit a brief, we do the matching, and vetted contractors quote your actual project.
Step 1: Submit your brief
Tell us your London borough, your property type, what you want to achieve, and your approximate budget. Three minutes. No drawings required. No specification document. A clear description in plain language is enough.
Step 2: We match and send your brief
QuoteMyRenovation reviews your brief and matches it against our vetted contractor network, filtering by trade, project type, and borough experience. We send your brief to a shortlist of up to three contractors who have completed comparable work in your area.
Step 3: Vetted contractors contact you
Each contractor reviews your brief before reaching out. They know what the project involves, where the property is, and what type of building they will be working in before they contact you. You receive quotes from builders who have chosen to quote your specific project, not from everyone who bought a list of leads that week.
QuoteMyRenovation is free for homeowners from brief submission to quote comparison.
London renovation costs sit above the national average; materials, labour, and the complexity of period properties all push prices higher. Understanding realistic cost ranges before quotes arrive is the best protection against accepting a price that was never going to cover the full scope.
The table below covers typical all-in costs for the most common London renovation projects. These are real-world ranges based on projects across Central and South-West London, not base prices to which structural works and planning fees are added as variations later.
| Project Type | From | To | Notes |
|---|---|---|---|
| Kitchen renovation (refit only) | £12,000 | £35,000 | Within existing footprint, no structural works |
| Bathroom renovation | £7,000 | £30,000 | En-suite from £7k; main bathroom from £10k; high-spec to £30k |
| Side return extension | £45,000 | £80,000 | Typical SW London Victorian terrace; glazed roof over side return |
| Rear single-storey extension | £50,000 | £120,000 | Includes structural steel, bifolds, and building regulations |
| Rear double-storey extension | £90,000 | £160,000 | Planning permission required; more complex structural works |
| Dormer loft conversion | £47,000 | £90,000 | Victorian terrace; includes staircase, bedroom and bathroom |
| Mansard loft conversion | £90,000 | £130,000 | Conservation areas; planning permission always required |
| Basement conversion | £80,000 | £200,000 | Waterproofing, underpinning, drainage; party wall obligations |
| Full house refurbishment (2-bed) | £90,000 | £180,000 | Kitchen, bathrooms, electrics, heating, decoration throughout |
| Full house refurbishment (4-bed+) | £180,000 | £450,000+ | Period property, Central London; all structural and finishing works |
All costs are approximate London all-in ranges (2024–2025). Prices vary by borough, property type, specification, and structural complexity. Get three matched quotes for your specific project.
All costs are approximate. Final price depends on borough, property type, specification, access, and structural complexity. A Victorian terrace in Battersea and a mansion block in Pimlico will produce different costs for the same scope of work.
Getting three matched quotes from contractors who know your borough is the only reliable way to price your specific project. That is exactly what QuoteMyRenovation provides.
Renovation Contractors by London Borough
QuoteMyRenovation covers renovation projects across London. The pages below go deeper on local planning rules, typical property types, the most common renovation projects in each area, and what to expect from contractors who know the borough.
South-West London
Renovation Pimlico – Victorian Cubitt terraces, Westminster stucco, and period property renovation on the north side of the Thames. Pimlico sits entirely within Westminster, one of the most active planning authorities in London. Side returns and loft conversions are the dominant projects.
Renovation Fulham – The side return extension is Fulham’s signature project. SW6 Victorian terraces were built without side access, and opening the kitchen into the side return changes the character of the whole ground floor. LBHF planning, 48 conservation areas, and a strong market for loft conversions above £60,000.
Renovation Battersea – Three distinct property types in one postcode cluster: Victorian terraces off Northcote Road, mansion blocks in SW8, and the Shaftesbury Park Estate conservation area. Rear kitchen extensions are Battersea’s highest-demand project. Wandsworth Borough approves 90.1% of planning applications.

London’s most efficient way to add a bedroom without extending into the garden. Dormer conversions on Victorian terraces, L-shaped dormers on semi-detached properties, and mansard conversions in conservation areas are the three dominant types. Planning requirements vary significantly by borough and property type. Costs range from £40,000 for a Velux conversion to £130,000 for a full mansard. Loft conversion London →
The single most-quoted project across South London. A rear extension replaces the single-storey outrigger or extends beyond the rear wall, creating an open-plan kitchen-dining space. Costs range from £45,000 for a straightforward single-storey extension to £150,000 for a large double-storey or complex structural project. House extension London →
Side Return Extensions
The gap between a Victorian terrace and its boundary wall, typically 900mm to 2m wide and the length of the ground floor. Infilling the side return with a glazed roof extension transforms a dark, narrow kitchen into a wide, open-plan space. The signature project across Fulham, Battersea, Clapham, and Balham. Costs from £45,000 to £80,000. Side return extension London →
Full House Refurbishment
A whole-property renovation covering structural works, kitchen, bathrooms, electrics, heating, decoration, and flooring throughout. The most complex project type and the most frequently under-quoted. Costs range from £90,000 for a two-bed terrace to over £400,000 for a large period property in Central London. House refurbishment London →

What Does "Vetted" Mean at QuoteMyRenovation?
Every contractor who receives leads through QuoteMyRenovation has been vetted before we send them any brief. Vetting is not a checkbox; it is a five-point review applied to every application.
Public liability insurance – Minimum £1 million, current and verifiable. We check the certificate, not the contractor’s assertion that it exists.
Trade credentials – Gas Safe registration for plumbers, NICEIC approval for electricians, FMB membership, or trade-specific qualifications relevant to the contractor’s speciality. The credential must be current, not lapsed.
Project history – Examples of completed projects in London boroughs. We ask for photographs where available and ask about the specific property types and borough areas covered. A contractor who has completed six rear extensions in Battersea is a different match from one who has completed six loft conversions in Islington.
References – At least two homeowner references from projects completed in the last twenty-four months, with contact details we can verify.
Borough experience – We map contractor experience by borough. A brief from a homeowner in Wandsworth goes to contractors with Wandsworth project history, not to the nearest available contractor who has never worked in that planning authority.
Contractors who pass vetting join the network. Contractors who do not pass vetting are not sent leads.
